Calculating Bar Velocity.

The goal is to get over 7m/s. 

I would like to calculate the m/s of the bar, when I am squatting, using the start position of the bar which would be at 76 cm and the end positing of 158 cm

To calculate the speed (in m/s) of the bar during your squat, we can use the following basic kinematic formula for velocity:

$$v=\frac{\mathrm{\Delta }d}{\mathrm{\Delta }t}$$

Where:

• $v$ is the velocity in meters per second (m/s),
• $\mathrm{\Delta }d$ is the change in distance (in meters),
• $\mathrm{\Delta }t$ is the time it takes to cover that distance (in seconds).

First, we need to convert your bar start and end positions from centimeters to meters:

$$\mathrm{\Delta }d=158\text{cm}-76\text{cm}=82\text{cm}=0.82\text{m}$$

Now, to find the velocity, we also need the time ($\mathrm{\Delta }t$) it took to move the bar from the start to the end position. Could you provide that information?

Say 0.25 seconds

Great! Now that we have the time ($\mathrm{\Delta }t=0.25\text{seconds}$) and the change in distance ($\mathrm{\Delta }d=0.82\text{meters}$), we can calculate the velocity:

$$v=\frac{\mathrm{\Delta }d}{\mathrm{\Delta }t}=\frac{0.82\text{m}}{0.25\text{s}}=3.28\text{m/s}$$

So, the bar's velocity during your squat is approximately 3.28 m/s.

What about 0.10

ChatGPT said:

If the time is $\mathrm{\Delta }t=0.10\text{seconds}$, we can recalculate the velocity using the same formula:

$$v=\frac{\mathrm{\Delta }d}{\mathrm{\Delta }t}=\frac{0.82\text{m}}{0.10\text{s}}=8.2\text{m/s}$$

So, the bar's velocity is approximately 8.2 m/s when it takes 0.10 seconds.
